An efficient, reliable, and cost-effective sensor for the sensing of 2,3-butanedione, an organic compound with a distinctive buttery aroma, is developed through the production of a sensible layer based on tin oxide semiconductor decorated with platinum nanoparticles. The resulting material is subjected to characterization and testing to evaluate its sensing capabilities towards 2,3-butanedione, known to be responsible of health risks upon inhalation, including the potential to cause lung disease, as well as to be detected in the breath of individuals with cystic fibrosis. The results demonstrate that the developed sensor provides a high sensitivity and selectivity towards 2,3-butanedione, in specific experimental conditions, featuring advantages such as simplicity, portability, and rapid response. In addition, it shows a great potential for on-site safety and health applications, providing a practical solution for real time monitoring.
